As an alternative to static cold storage (SCS), advanced perfusion techniques such as normothermic regional perfusion and ex-situ perfusion (normothermic or hypothermic) have emerged as a way to improve the ischemic injury suffered by donation after circulatory death (DCD) livers. Multiple studies have been published that have demonstrated superior post-DCD liver transplant outcomes when using advanced perfusion compared with SCS. In particular, these studies have shown lower rates of ischemic cholangiopathy with advanced perfusion. In addition to the improved post-liver transplant outcomes, studies have also demonstrated higher rates of liver utilization from DCD donors when advanced perfusion is used compared with SCS. Given the high rates of graft loss in patients who develop ischemic cholangiopathy, the significant reduction seen in DCD donor livers that have undergone advanced perfusion represents a key step in more broad utilization of these livers. With such compelling evidence from multiple trials, it seems reasonable to ask the question: should advanced perfusion be the standard of care for DCD liver transplant?
作为静态低温保存(SCS)的替代方法,一些先进的灌注技术,如常温区域性灌注和离体灌注(常温或低温)已经出现,旨在改善因循环死亡后捐献(DCD)而导致的肝脏缺血性损伤。已经发表了多项研究,表明与 SCS 相比,使用先进的灌注可以获得更好的 DCD 肝移植术后效果。特别是,这些研究表明,先进的灌注可降低缺血性胆管病的发生率。除了改善肝移植术后效果外,与 SCS 相比,使用先进的灌注还可以提高 DCD 供体的肝脏利用率。鉴于发生缺血性胆管病的患者移植物丢失率较高,因此,经过先进的灌注处理的 DCD 供体肝脏的显著减少,代表着更广泛地利用这些肝脏的关键一步。鉴于多项试验提供了如此有力的证据,我们有理由提出这样一个问题:先进的灌注是否应该成为 DCD 肝移植的标准治疗方法?
